tnost excellent artists. In this manner the reader will the 

 more easily recognise the parts which characterize the 

 worms h.ere described. 



I can guaranty tlic fidelity of the plates ; they exact- 

 ly resemble the originals, liaving compared them with tiie 

 samples, still visible in the celebrated collection of the il- 

 lustrious Goez.e, and which is preserved in the museum of 

 natural history of the University of Pavia. 



Estimating with impartiality the merit of tliosc natur- 

 alists and physicians who have devoted themselves to the 

 productions of nature, I have made it a sacred duty to re- 

 exhibit in my plates, such human worms as they have ex- 

 amined and described with great fidelity. 



The plates in the works of Bonnet, Marx, Fallas, Goeae^ 

 and Werner, are the most valuable and instructive of any 

 which have yet appeared relative to human worms. 



Of these plates, I have selected the most interesting, 

 and uniting them with the eniiravings of other worms 

 which I have found described, and which still remain in 

 the pathological Museum of the University of Pavia, I flat- 

 ter myself that I have presented in these five plates a rep- 

 resentation of the principal worms of the living human 

 body, in conformity to the Lectures, and which will be very 

 advantageous, particularly to those physicians who do not 

 possess the interesting works of the naturalists and phy- 

 sicians already cited.
